Abstract
A practical synthesis of phenanthridines is of considerable interest in the fields of organic and pharmaceutical chemistry, 1 since this basic skeleton is widespread in naturally occurring alkaloids and exhibits interesting biological activities. 2 Recently, a cascade radical pathway involving C-radical addition to 2-isocyanobiphenyls and subsequently intramolecular homolytic aromatic substitution has been developed, which allows the rapid assembly of a phenanthridine ...
